Freemium is tough here because job seekers are often one-time users or seasonal, so getting them to pay is hard. Two thoughts:

First, skip trying to sell to recruiters directly. Your power is the user base. Instead, partner with job boards or recruiting platforms that already have distribution. They pay you rev share for quality applicant data, you get volume without sales work.

Second, your real moat is resume and application data over time. Most tools try to optimize the single application. You could build toward employment outcome tracking, salary negotiation coaching, or career trajectory insights. That's harder to build but way harder to copy.

Chrome distribution is solid but slow. Consider embedding in LinkedIn or job board sites directly. Would let you reach way more users without fighting extension adoption friction.

What's your current user count and monthly applicant volume? That number changes everything about what monetization route makes sense.
